Fastening and adjusting device, particularly for ski boots

Abstract

Fastening and adjusting device, particularly usable in ski boots comprising a winder for at least one traction element. The peculiarity of the device consists in the fact that a skier accessible knob is associated with said winder and has a first seat for a temporary locking element for locking to a body associated to said boot. Both the knob and the winder respectively have a second and third seats for a releasing element, for releasing said knob and body, and for a resilient member.

I claim: 
     
       1. Fastening and adjusting device, particularly for ski boots, comprising at least one winder for at least one traction element and a skier accessible knob, said knob being connected to said at least one winder, said knob having a first seat for a temporary locking element for locking to a body which is rigidly connectable to said boot, said knob and winder having a second seat and a third seat respectively for a releasing means of said knob from said body and for a resilient member, said releasing means comprising a pushbutton at one end partially protruding outside said knob and at another end interacting with said resilient member located at said third seat formed in said winder and communicating with said second seat formed in said knob, said winder being constituted by a spool having one or more annular races for said at least one traction element, said at least one traction element comprising a cable, said knob being substantially circular, said temporary locking element being a pawl which is arranged in said first seat of said knob, said first seat being substantially L-shaped, wherein said pawl is substantially L-shaped and has a bigger first wing hinged by means of a pivot inside said first seat at a junction with a smaller second wing, and wherein said first wing has an end located at a groove formed on said pushbutton, said body being provided with an annular toothing which faces said knob, said second wing being forced to interact with the annular toothing of said body by means of said resilient member. 
     
     
       2. Device, according to claim 1, wherein said substantially L-shaped first seat has wings perpendicular to each other, one of said wings being perpendicular to a center rotation axis of said knob. 
     
     
       3. Device, according to claim 1, wherein said winder has a first leg associated with a second leg of said knob, said body being rotatably associated with said second leg, said body being rigidly connectable with said boot. 
     
     
       4. Device, according to claim 1, wherein said pushbutton is slideably associated in said second seat, said pawl interacting as a catch with said annular toothing.
